New concept sulcus-implanted IOL may provide true accommodation in presbyopic eyes

A novel sulcus-implanted lens based on free-form optical surfaces showed promising results in providing patients with 2 D to 5 D of true accommodation.
The AkkoLens Lumina is a hydrophilic acrylic IOL made of two optical surfaces that shift perpendicular to the optical axis thanks to vectorial forces generated by the ciliary body during the accommodation process, OSN Europe Edition Board Member Jorge L. Alió, MD, PhD, told Ocular Surgery News.
“The magnification and power of the lens change, allowing the patient to focus at different distances,” he said.
One-month results in 27 eyes of 27 patients implanted with the Lumina at the Resbiomed Eye Clinic in Sofia, Bulgaria, showed a range of accommodation from 2 D to 5 D. Most defocus curves showed a flat high-profile plateau, up to 3.5 D at 20/20 visual acuity, very similar to that of young eyes with a natural lens.
All the surgeries were performed by Alió, with the lens implanted in the sulcus through an incision of approximately 2.8 mm.
“This is the very first time that true accommodation is demonstrated with a sulcus-based lens on sighted eyes. Some of the patients have now achieved 2 months of follow-up and continue showing excellent results with no complications,” Alió said.
